The MXR Custom Shop brings back that highly sought after sound with the '76 The Vintage Dyna Comp. This pedal tightens up a guitar signal, raising the volume of the quiet notes and leveling off the peaks to create a rich, full bodied sustain. It features the exact same circuitry used in the original 1976 DynaComp, identical in its component layout, silkscreen and handmade wire harness.
